“We fully expect that some donors gave strictly to support Newt and will not want to support a different mission,” said Chuck Muth, a Las Vegas-based consultant working for Winning Our Future. But he said past donors “will be asked to continue supporting our efforts going forward” and predicted “if we make a compelling case for sticking with us, some will.”

Sources close to Adelson, who spent in the ballpark of $100 million trying to elect Republicans in 2012, say he hasn’t signaled which political efforts he’ll support for 2014.

Winning Our Future is not alone.

A number of super PACs that formed specifically to support candidates in the 2012 elections are grappling with the question of what to do now — and to figure out what to do with their cash.

Priorities USA Action, which was devoted to President Barack Obama’s reelection campaign, hasn’t signaled what it’s going to do with the $3.7 million it had in the bank at the end of the year, while the pro-Mitt Romney Restore Our Future super PAC, which had $1.3 million, has been similarly mum about its plans.

Winning Our Future doesn’t have nearly as much cushion.

It finished 2012 with only $60,000 in the bank after refunding $5 million to Adelson’s family.

The super PAC paid a total of $30,000 last month to Muth and Gregg Phillips, who is running the PAC, and finished the month with only $26,000 in the bank.

Both men worked for the PAC during the 2012 GOP presidential primary, but the operatives closest to Gingrich and his donors — strategist Rick Tyler and fundraiser Becky Burkett — have cut ties.

Winning Our Future is considering a number of options, Muth said, including playing in 2014 Senate races and working to build grass-roots mobilization infrastructure — an area in which conservatives agree they were outclassed in 2012.

Muth said he is preparing a survey to gauge the interests “and possible future involvement” of donors who supported Winning Our Future’s pro-Gingrich efforts. And last week he sent a 20-page manifesto of sorts to the list entitled “The Ultimate Field Guide for Political Foot Soldiers.”
